SPECIFICATION forming part of Letters Patent No. 417,865, dated December24, 1889.v Application filed September 11, 1889- Serial No. 323,668. (Nomodel.)

T0 whom it may concern:

Be it known that 1, CHARLES J. GREEN, of

Placerville, El Dorado county, State of California, have invented anImprovement in W'ater-Wheels; and I hereby declare the i'ol lowing to bea full, clear, and exact descrip tion of the same.

My invention relates to certain improve ments in that class of wheelsknown as n10- mentum or hurdy-gurdy wheels; and it consists in bucketsadj ustably arranged upon ter which is discharged into the first andsecond buckets.

Referring to the accompanying drawings for a more complete explanationof my invention, Figure 1 is a View showing a portion of the rim ofawheel with my buckets arranged thereon. Fig. 2 is a vertical section ofthe rim withits buckets. Fig. 3 is a transverse section.

In this class of wheels the buckets are made of such form that the waterwhich is discharged from the nozzle under ahigh pressure is receivedinto the buckets so as to pass around the concavity of the bottom. andbe discharged at the outer edges, this being a common form ofconstruction in several wellknown wheels.

In my invention I have improved the c011- struction of the wheel bymaking these buckets transversely adjustable to and from the center ofthe rim of the wheel and placing them with relation to each other sothat the stream of water is always divided between two buckets, one ofwhich is behind theother.

A is the rim of the wheel, which is formed with transverse dovetailedslots B in its periphery at such a distance apart that the buckets 0 maybe fixed to the aim by means of dovetailed projections D, which are castupon the buckets and adapted to slide in these horizontal dovetailedslots. The inner face of the wheel-rim has slots E beneath and parallelwith the dovetailed slots in the outer face, and through these slotsscrews 15 project. The inner ends of these screws are fixed in thedovetailed slides of the buckets, and the ends which project through theslots are screw-threaded, so as to receive nuts G, by which the bucketsare clamped in any position in which they may be placed, or the bolts Fmay screw directly into the slides of the buckets, the heads abuttingupon the sides of the slots E. The slots in the outside wheel-rim, intowhich the slides of the buck ets fit, are made alternately from theright and from the left edges, so that the buckets are set inalternately from one side and the other. The inner edges of the bucketsare made thin, and the interiors of these buckets are curved and madeconcave, so that the water striking into either of the buckets passesaround the curved bottom of the concavity, thence up the outside, anddischarges over the outer edge of the bucket, as is usual in this classof buckets.

In my construction I fix. each alternate bucket in its transverse slotso that the inner edges of the buckets stand at such relation to eachother that the water from the nozzle will strike partly in the bucketwhich is presented nearest to the nozzle and the re mainder in thebucket which is just behind the first one. By this relative arrangementand alternation of the buckets I am enabled to place them closertogether than when the buckets are placed upon the wheel one directlybehind the other. The object of this construction is to enable theoperator to start the wheel with less delay than in the ordinaryarrangement of the buckets.

This class of wheels is very largely used for hoisting purposes, and areconnected directly with the hoisting mechanism, it being usual to startand stop the wheel with the rest of the machinery, and consequently thisoperation takes place very frequently during the day.

If the bucket is at a considerable distance from the nozzle, as would bethe case in the ordinary construction of the Wheels, it is oftennecessary to put the foot on the wheel to assist it in starting, andsome delay and loss of water occur with each operation of this sort. Bymy construction one bucket is always as close to the nozzle as possible,and ready to receive Water therefrom, and by discharging a portion ofthe water into the bucket behind it I have found that the wheel willstart more readily and that a better result is attained.

By means of the transverse adjustment of the buckets I can set thebuckets so that the first and second ones will receive each onehalf ofthe Water from the nozzle; or the first one may be set so as to receivetwo-thirds or any other proportion of Water from the nozzle, theremainder discharging into the bucket behind, as above described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a water-wheel, the rim having the buckets secured alternately uponits outer periphery and having their inner edges standing with relationto each other and to the nozzle so that a portion of the waterdischarged from the nozzle is received by the bucket nearest to thenozzle and the remainder by the bucket just behind this first one,substantially as described.

2. In a Water-Wheel, the rim having transverse slots made alternatelyfrom the opposite sides of its periphery, buckets having tongues orslides fitting in said slots, and movable so as to adjust the buckets toor from the center, substantially as described.

3. In a water-Wheel, the rim having the outer periphery formed withtransverse grooves or slots, corresponding slots extending through thebottom of these outer slots to the interior of the .lilll, incombination with concave buckets adapted to receive water at the inneredges and discharge it from the outer edges, said buckets being providedwith tongues or slides fitting into the transverse slots, and screws andnuts whereby they may be adjusted with relation to each other and lookedupon the rim of the Wheel, substantially as described.

In witness whereof I have hereunto set my hand.
